Diabetic kidney disease (DKD) is a type of chronic kidney disease (CKD) caused by diabetes. The clinical diagnosis of DKD is usually based on the presence of increased albuminuria and/or decreased estimated glomerular filtration rate (eGFR), and exclusion of other causes of CKD. The clinical features of DKD are proteinuria, gradual decline in renal function, and severe renal failure in the later stages, which is one of the main causes of death in patients with diabetes. Any single biomarker might be insufficient to evaluate renal injury; thus, multiple methods and markers are needed. In addition, diabetic patients should be paid more attention to the kidney, and kidney damage should be evaluated with standardized assessment aimed at strengthening the early prediction and diagnosis of DKD.

Objective To investigate the functional changes of dendritic cells (DC) in elderly patients with sepsis. Method Elderly patients (n = 20), ages 75 to 86 years, treated in the department of internal medicine for cadres and the medical intensive care unit (MICU), were selected to participate in the study. Patients with ma-ligoant tumors, hematological diseases, immune diseases, or a history of receiving drugs known to interfere with immune functions were excluded. Using the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) definition of sepsis, the patients were categorized into four groups: non-sepsis (group A) (n = 5) ; sepsis (group B) (n = 5) ; severe sepsis (group C) (n = 5) ; and septic shock (group D) (n = 5). The peripheral blood mononuclear cells (PBMCs) of each patient were isolated and cultured with human re-combinant granuloceyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in vitro for 10 days. The cells were examined under an inverted microscope, scanning electron microscopy, and flow cytometry. The MTT colorimetric assay was used to observe the abilities of the dendritic cells to stimulale an allogeneic T lym-phocyte response in vitro. Paired t -test was used to compare changes in the surface markers among the different groups, Results The PBMCs in the four groups of patients differentiated into cells with typical dendritic configura-tions after in vitro cuhure with combined cytokines. The CD40, CD80, CD86, and HLA-DR expressions on the cell surfaces increased after culture,with (43.2±12.5)%/(27.3±9.3)%, (31.4 ± 10.1)%/(22.5 ± 8.7)%, (39.3±15.7)%/(21.9±7.7)%, and (75.4±25.6)%/(58.7±16.7)%, respectively. The stimulation index (the abilities of the dendritic cells to stimulale the allogeneic T lymphocyte response in vitro) in the four groups of patients after culture were (23.3±7.9) in group A, (18.9±8.3) in group B,(11.4±5.1) in Group C,and (5.5 ± 3.7) in Group D. Conclusions The immune functions of the dendritic cells of elderly patients with sepsis decrease in a linear manner with the severity of their septic state.

Objective To analyze the invasion and metastasis of endometrial stromal cells in endometriosis through assessing the transcription levels of COX-2, PGE2, Snail and E-cadherin mRNA. Methods Ectopic and eutopic endometri?al tissues from patients with EMs (endometriosis) or uterine fibroids were collected and cultured. The fourth generation of pu?rified endometrial stromal cells were used for research, and the transcription levels of COX-2, PGE2, Snail and E-cadherin mRNA were analyzed by RT-PCR. Results There were no statistical differences in transcription levels of COX-2, PGE2, Snail and E-cadherin mRNA in eutopic endometrial stromal cells from patients with EMs or uterine fibroids between secra?tion stage and proliferation stage(P>0.05). The transcription levels of COX-2, PGE2 and Snail mRNA were significantly in?creased while transcription level of E-cadherin mRNA was decreased in eutopic and ectopic endometrial stromal cells in pa?tients with EM compared with those in patients with uterine fibroid. And the difference was statistically significant(P<0.05 or P<0.01). The transcription levels of COX-2, PGE2 and Snail mRNA were obviously higher while transcription level of E-cadherin mRNA was lower in ectopic endometrial stromal cells than those in eutopic endometrial stromal cells from pa?tients with EMs. And the difference was statistically significant(P<0.05 or P<0.01). Conclusion The invasion and me?tastasis of endometrial stromal cells of patients with EMs were remarkable than those cell of patients without EMs. What ’s more, the invasion and metastasis in ectopic endometrial stromal cells were more obvious than those cells in the pathogenesis of EMs.
